This number tells us how many people would live within one square mile if the U.S. population were evenly distributed across its land area.
In a nutshell, Antarctica is experiencing some drastic changes. The most drastic of which include climate change, where the climate is getting hotter, due to some natural causes. The result of this is the ice melting which can make some species such as polar bears, penguins, and seals extinct, due to not having anywhere to migrate to, them not being 100% sea animals.
Antarctica is located in the south pole of the Earth, directly under the north pole (Arctic). These changes are also present in the arctic.
The reasons as to why the Indo-Europeans migrated to Europe were the better climate conditions, more grazing land and fertile soil, and overpopulation.
Explanation:
The Indo-Europeans were a group of people that formed and lived in the Eurasian Steppes, mostly in the lowlands of what is now Central Asia. Central Asia though was not offering the best living conditions, as the climate was harsh, fertile soil, was lacking, the grazing lands were limited, and the population of the Indo-Europeans was constantly growing. This made numerous groups of these people to migrate in several waves toward other regions, including Europe.
Being a war-like people and superior in combat, the Indo-Europeans found it easy to move into the European territories and settle in. The migration waves were mostly going through the lowlands north of the Black Sea, and through Anatolia and the Balkan Peninsula. Very quickly the Indo-Europeans managed to become dominant in Europe, establish their culture, language, and beliefs.
The main reason for migration were:
- overpopulation
- better grazing lands
- fertile soil
- better climate
Ethnic families that are believed to have originated from the Indo-Europeans are:
- Celtic people
- Germanic people
- Slavic people
- Baltic people
- Italic people
- Daco-Thracian people
- Illirian people etc.

I think the correct answer to this is ‘reduced prey
quality’.
<span>This is because in the study made by Trites and Donnelly,
they found out that steller sea lions were experiencing nutritional stress.
Nutritional stress means that although the prey contains all the necessary
nutrients, the quantity of prey is not enough due to a reduction in overall
biomass of prey locally. </span>
